The Mercedes-Benz SL65 AMG, absent from the automaker’s 2012 product mix, is arguably one of the best grand-touring roadsters on the planet, and the new 2013 model manages to improve on what’s always been a very good product.

Set to debut at next month’s New York Auto Show, the new SL65 AMG gets refined styling, a lighter curb weight, a redesigned interior and an improved twin-turbo V-12 mated to an all-new, seven-speed SpeedShift Plus gearbox.

The car’s 6.0-liter V-12, while based on the previous SL65’s engine, receives significant updates. There are new turbochargers, new manifolds and a revised exhaust system that add up to a 17-horsepower jump in output. Optimized cylinder heads work with a revised ignition system and a remapped ECU to provide lower emissions, too.

While the list of standard features is extensive, buyers can also choose to personalize their SL65 roadsters with unique paint options, including several matte finishes. Carbon ceramic brakes are on the list, as are carbon fiber trim pieces to improve the SL’s aerodynamics.

As the video shows, the SL65 AMG looks great parked in the driveway of your architecturally-significant home, or driving the winding canyon roads necessary to reach it. If you’ve got the price of admission, the SL 65 AMG is a serious reward for your hard work and accomplishments.

We'll bring you details of the car's launch as part of our complete 2012 New York Auto Show coverage.
